cool! I get 1 dark brown speckled egg a day from an Australorp,. Purple would be too cool! What breed is laying it?

The breed is a new hampshire crossed barred rock, I believe. They came as a "hatch day choice" in my last order so it was a surprise as to what they would be. They are they speckled egg layers, there are 3 of them laying speckeled eggs, but one one lavender one.
It may sound cool, but everyone in my family looks at them weird, or tryes to clean them off insisting my husband is playing a trick on me. But I have seen her lay them.​
